WV>Michael,
WV>Since  is often replaced by a CRLF sequence I 
WV>suggest you use the following definition for enter :
WV>char enter[] = "\n";

WV>and for the call:
WV>DosWrite(hFile, enter, strlen(enter), &ulBytesWritten );

WV>"\n" actually may be 2 characters, but I am not sure about that.

  "\n" is a line feed character in all C compilers that I've seen.  Writing
a "\n" to a serial port will not do you any good in dialling a modem,
writing a carriage return (character 13) will work.  If you want to write a
DOS new-line then do the following DosWrite(hFile, "\xd\xa", 2,
&ulBytesWritten).  That works and I use it in my programs.
